Ok… Wow! how bizarre! This all works fine on OSX … but I have now discovered that the above XML scripts do NOT work anymore on Windows 10!!! I had Chrome as my default browser, which means it will either open a local PDF file in the browser (chrome will not interact with Adobe now) , or make you download it (which makes absolutely NO sense!). I tried switching default browser to Edge… Your ONLY option is to open it in a browser. PDF on Windows is quirky! I can’t figure out any way to get Edge (or Chrome) to open the document in Adobe! Since the XML tags are . Anyone know of a different XML tag that might fix this? Not Steinberg’s problem… It’s an old fight between Google, Microsoft and Adobe.
